Alright, small update. From what my VW friends say there is a Regulator for the ECU. Since my car gets grumpy below 15v but above 14.5ish they are suggesting they my ECU Regulator might be going out. A simple modification to make the car accept 15v charging is to add a load resistor with a heat sink to the ECU power line in the harness.
So, I'm going to look into that but the ECU should be happy at anything below 15v. That means I can charge at 14.8v with a harness mod and run 6s LTO and get 75-80% of their capacity. I will need to figure out some kind of balancer that works at that lower voltage threshold, but that's a project for another day.
The alternator shop is trying to figure out what parts they can actually get to build the alt so no more information on that yet.
